我正在创建一个应用程序,在其中我需要制作一个清单,其中有一个从另一个类给我的列表。用户将选中所需项目旁边的复选框,然后单击按钮。对于那些被检查的行,我想在相邻的QBoxGroup的QLabel中打印“youcheckednumber”
(在我的实际应用程序中,我遍历类,在类中调用类中的函数)。我很难遍历我的列表,因为我必须检查这个框是否被选中,以及名称是否是我想要打印的名称(打印的语句与实际名称不同,因为在我的应用程序中,我将调用我所在行的类中的函数)
如果用户用QLabel选中多个框,我也不知道如何处理这个问题,因为我可以打印多个语句。我可能不得不让用户一次只能选择一行,但这比上面的问题要小

我尝试了这些StackOverflow页面上的信息,但似乎不知道如何查看行的名称以及是否选中了行:
正如我在注释中指出的,您有一个类型,因为您有一个名为
self.model
的属性,但您希望使用self.model()
进行访问另一方面,您的逻辑是不正确的,因为例如它没有被定义为
row
,另一方面,假设这个错误不存在,并且您的逻辑检查了2个选项,您正在编写“您检查了数字X”,然后将其替换为“您检查了数字Y”其逻辑是将选中项目的文本保存在一个列表中,如果该列表不是空的,则连接信息,否则表示没有选中项目
